[0002] Traditional curtain stands bring a lot of trouble to users due to their large size. When it is necessary to move it, users may feel very inconvenienced because the whole stand is bulky and difficult to carry easily. In addition, storage is also a problem because its size takes up a lot of space, making it difficult for users to find a suitable place to store it.

[0003] During transportation, especially when it is necessary to carry it over long distances or take public transportation, the large-volume bracket may cause a lot of trouble to the user. Sometimes, the user even needs to disassemble the bracket to put it in the car or on public transportation, which undoubtedly increases the burden on the user.

[0004] Therefore, some improvements are needed in the traditional curtain bracket. Utility Model Content

[0005] In view of this, the utility model provides a projection screen bracket, which is small in size and easy to carry, providing great convenience for users, and is not only small in size but also has good firmness.

[0020] The right inflatable support has a trapezoidal shape, and the third magnet is arranged at the four corners of the left inflatable support. This design makes the right inflatable support and the left inflatable support form a symmetrical structure, making the bracket more beautiful visually. At the same time, the trapezoidal structure further enhances the stability and load-bearing capacity of the bracket.

[0021] Preferably, the second magnet and the fourth magnet are respectively arranged at the left and right ends of the middle inflatable connector.

[0022] The second magnet and the fourth magnet are respectively arranged at the left and right ends of the middle inflatable connector, so that the left and right ends of the middle inflatable connector can be respectively connected and fixed to the left inflatable support and the right inflatable support.

[0023] Preferably, the first magnetic strips are in the shape of long strips, and there are four of them, and the four first magnetic strips are located in the same plane.

[0024] The first magnetic strips are in the shape of long strips, and there are four of them, and the four first magnetic strips are on the same plane. This design makes the first magnetic strips have a strong load-bearing capacity and stability, and can better support the projection screen.

[0025] Preferably, the second magnetic strips have the same shape as the first magnetic strips, and there are four of them, and the positions of the four second magnetic strips correspond one-to-one to the first magnetic strips.

[0026] This enables the second magnetic strip to perfectly cooperate with the first magnetic strip, further enhancing the stability and load-bearing capacity of the bracket.

[0027] Compared with the prior art, the utility model has the following beneficial effects:

[0028] The projection screen bracket of the utility model and the design of the inflatable support frame enable the projection screen to be easily supported, and due to its inflatable characteristics, it is compact and easy to carry, providing great convenience for users.
